Two Samplers One Drum - Elektron Digitakt, Volka Sample and Sansamp Flyrig

Published on Dec 29, 2019 Mauricio Maisterrena

"The Volca is doing almost al the rythm section and is going through the flyrig for some overdrive, the Digitakt is sequencing everything and doing all the melodies."

Some free style playing at 1:53.

Crumar Bit One MIDI Upgrade demo

Published on Dec 29, 2019 Harry Axten

"This is a modification I developed for the Crumar Bit One, a fairly rare Italian-made polysynth from the mid 1980's, that improves its MIDI capability. The upgrade takes the form of a small daughterboard that installs neatly inside the synth. More information can be found at"

ARP PRO/DGX Model 2733

via this auction

"Meticulously overhauled over a whopping 32 hours (!). They usually don't take us this long, but this one had a tricky problem in the digital oscillator section that required a lot of time to sort out. In addition to performing this and any other repairs, we did the following work to this unit:

Touch sensor was replaced with a new one and adjusted. These are usually not working at this point in time.
Power supply capacitors replaced to extend life.
Keyboard rebuilt: replaced bushings, cleaned key contacts and removed and cleaned/polished bus bars.
Removed, adjusted, cleaned, lubed and reinstalled all slide pots.
Cleaned and lubed all switches.
Adjusted tuning.
Cleaned inside and out.

Thanks to all the time, love and money we invested in this unit, it is now working like new again, is totally ready to play, and will hopefully continue to work for a very long time, which makes it a much better purchase than others of its type on the market."

CES Ed-Lab 703a Digital Systems Lab

via this auction

"These units were produced for educational purposes but as you can see they are easily integrated in to a banana cable modular synth set up (eg Buchla, Serge, Modcan A, Phenol, Fenix, Bugbrand, Lorre Mill, Ciat Lombard etc)

It's a collection of various logic, digital and simple AD/DA circuits with a few analog sections and a HEX input key pad.

I've seen them advertised as "Analog Computers" which of course they are not, but I can see why some folk might think so.

I intended to use this with my Serge system but never got around to it and now I need the space.

The high/low switch for the digital clock speed needs replacing."

"One works perfect and is in wonderful cosmetic shape. The other one powers up, plays the rhythm section but the keyboard doesn’t work. So one works perfect and the other is for parts. The parts one is missing the battery cover."

TAMA Techstar TS204 Analog Drum Synthesizer w/ Hand Clap SN 201075

via this auction

"This is a cool rack unit that can be triggered via pad or a trigger pulse from something like the Arturia Beatstep Pro or Behringer RD-8 drum machine. I have used both to trigger it as well as Simmons pads. The hand clap can't be tweaked much, but it's nice and clappy. The Synth on the other hand is bonkers. It has a longer release than any other Techstar drum sound. I have one of the bigger 6 channel Techstar units as well and this one is the longest. It has an LFO which no other Techstar sound has either."

DivKid Ochd w/ Manis Iteritas | LFO Chaos

Published on Dec 29, 2019 Nostalgic Ruckus

"Been waiting for something like this for the skiff. Luv my clock dividers and multipliers and this kinda does it with LFOs. Cranking that rate knob is a beautiful thing. The Manis with all the patch cables is being modulated by Ochd only. The other Manis output is plugged into the E440 filter to tame some unwanted harmonics but also add some resonance when Ochd gapes the envelope. Attenuating Ochd's outputs with Bored Brain Splix. The CV input on this thing is crazy cool when self patching it just didn’t do it on this patch."

POLYGOGO Stereo Oscillator - Sound Demo #2 - Eurorack Modular Synthesizer

Published on Dec 29, 2019 MIKE LEE BIRDS

"In the previous video I used the amazing POLYGOGO as sort of a drone/soundscape machine.

Here it‘s hooked up to the beautiful TUESDAY procedural sequencer from „This Is Not Rocket Science“.
The fold circuit serves as a VCA and is fed an envelope from MATHS. That same envelope goes into the OP (internal FM) Amount input for a quasi-sort-of-filter idea.

About the fold-VCA thing:
I noticed that feeding a negative voltage into the fold circuit and turning the attenuator to between 2 and 3 o‘clock will silence Polygogo. A positive voltage can then control the volume, hence Maths.
More clearly: Maths channel two is sending negative voltage (knob at 9 o’clock) through the sum output and channel one adds an envelope triggered by Tuesday.

- CHANCE changes polygons.
- MONSOON (Clouds) is responsible for reverb and adds pitch shifted delay later on.
- BEAST’S CHALKBOARD does some octave shifting off screen.
- PEAKS provides bass drum and hihats triggered by Tuesday’s beat and ticks outputs respectively. Sorry for the clipping bass drum.."

ARP ODYSSEY 70s Mk1 White Refurbished & Future-Proofed

via this auction

"Fully Refurbished & Future-Proofed, sparing no expense. This process took a whopping 23 hours of skilled labor. Part of this time was spent attempting to rebuild some of the original potentiometers, but they didn't meet our high standards after our efforts (they usually don't), so we decided to replace them all with new ones. In addition to a full servicing, we took preventative measures so this Ody will hopefully outlast all others out there. The work we did included the following:

Full disassembly and deep cleaning inside and out.
Power supply rebuild.
Replacement of all tantalum capacitors.
Removal and replacement of all rubber key bushings.
Cleaning of all key contacts.
Cleaning of bus bars.
Adjustment of keys.
Replacement of all potentiometers (approximate parts cost $300)
Cleaning of all switch contacts.
Replacement of power cord.

Post-restoration, this unit works like new again and is a real pleasure to play. Sure to make its next owner really happy. This unit is much better than the rest and is priced to reflect the investment we made to make it better than others on the market.

New Motion Soundscape Classic FX Coming Next Year

via Motion Soundscape

"A new app is on the way. Classic FX - Reworked classic audio effects units.

This app consists a lot of different simple audio processing units like filters, delay, chorus, panner, vibrato, etc. The algorithms are define connections between these units and construct more complex effects. The presets integrate the algorithm and parameters of the processing modules. So you can have several options of using the same algorithm with different parameters.

You can choose two different presets and morph between them manually or cycle mode. Sophisticated morphing smoothly transforms one algorithm into another and can create stunning transition effects.

To give more dynamic, it is possible to change the effects depending on the level of the input signal, as well as make changes related to the rhythm using the internal step sequencer.

This app will support AUv3, Inter-App audio (Audiobus) and work as standalone audio processing app. It will be universal app for iPad and iPhone. No in-app purchases, no subscriptions.

Happy New Year!"

【PLAN B #91】東郷清丸 × kauai hirótomo #3 Published on Nov 21, 2019 SPACE SHOWER TV

Used as a guitar synth.

via this auction

"I played this instrument using the MIDI out
provided by Roland's guitar synthesizer.

- - -

Although it was a digital synthesizer,
it produced the sound of a very thick oscillator,
yet had a delicate treble feel, and I liked and used
the space-like sound."

Waldorf Quantum

via this auction

"This Quantum is unplayed. In fact the blue plastic protective film is still covering the display.

Quantums have a usage clock in the Global menu like an odometer which still reads somewhere between roughly 29-45 minutes (less than an hour) of power-on time. This was from the factory where the unit was burned in, which all are."

Thought that was interesting. Wish all synths had this. :)

Siel DK80 1984 Analog Synthesizer w/ SSM2045 Filters

via this auction

"A lot of love went into this machine. All capacitors have been replaced by new, high quality, low ESR ones by Nichicon, Panasonic, etc. The power supply section was upgraded. A new power supply module was fitted. All keys were cleaned. Comes with a RAM module.
This machine sounds amazing. Lush, full-bodied, dirty when pushed. And the retro eighties looks are stunning. A real asset to your setup!

It features:

- Bi-timbrality
- Velocity sensitivity on a really good keyboard (Fatar)
- 8 voices of polyphony
- Chord memory
- Stereo output, stereo chorus"

POLYGOGO Stereo Polygonal Oscillator Sounds - Eurorack Modular Synthesizer

Published on Dec 28, 2019 MIKE LEE BIRDS

"A first wiggling session with the about-to-be released POLYGOGO Polygonal Stereo Oscillator by E-RM Erfindungsbüro.

It’s an incredibly intuitive and hands-on module with tons of soundscaping capabilities.

The screen beautifully visualizes the modulations and sonic changes. I find it very useful for understanding what‘s going on with the knobs and sliders.

Polygogo is running through Clouds/Monsoon‘s reverb. At 4:25 Clouds starts doing its thing with a bit of pitch shifting for good measure."


Philip Glass' Opening from Glassworks on Modular Synthesizer

Published on Dec 28, 2019 musicartgeek

"A lot of liberties taken here, but it's based on the opening from Philip Glass' seminal Glassworks. I like to think of it as a pencil sketch by a student sitting in front of a masterpiece in the Met.

One of many departures from the original that I made was rather than the two over three metre of the original (or is it three over two? it keeps on changing!), I used a Doepfer Clock Divider to arbitrarily assign gates to the five voices using only prime number ratios for the rhythmic divisions, in this case 5, 7, 11, and 13, but I cheated with the 4 underneath! The final moments are given over to the Doepfer 154/155 Sequencer system, creating one-shot aleatoric figures."

"Some tips for the ODLPG from Cavisynth."

"This module was designed and assembled in Switzerland by hand and with love.

“ODLPG” = Opto – Disto – Low – Pass – Gate

ODLPG is a lowpass gate whose circuit is based on the diversion of an optocoupler usually used to electrically isolate two circuits.

In other words: it is a vactrol that controls the opening of the VCA and the filter at the same time, giving a particular roundness to the sound.

In addition, this circuit architecture extremely simple, adds a little distortion when the CV that comes from your EG is quite strong.

The “curve / drive” knob increases the opening of the filter and the (light) saturation value at the same time.

The panel is matte black (like the Bufflide)

Technical specifications:

Format – Eurorack
Power consumption – 10mA [-12V] // 10mA [+12V]
Module width – 4HP (20mm)
Module depth – 12mm (Skiff super friendly)
Weight – 35g"
